Hawaii in March: Spring Break, Whales, and Warm Weather

March is a month of contrasts in Hawaii. Early March offers some of the best conditions of the winter season: warm weather, active whale watching, and less pressure than February. Late March is one of the most crowded and expensive periods of the year because it coincides with spring break for universities and many school districts. Knowing which week you will travel shapes the entire experience.

Weather in March

March temperatures are warm and consistent: 79-83°F (26-28°C) during the day, with ocean temperatures around 74-75°F (23-24°C). Trade winds are generally steady, though Kona wind conditions (warm, humid, southerly air) occur more frequently in March as winter transitions toward summer patterns. Windward coasts still see occasional rain showers; leeward coasts remain reliably sunnier. By late March, days are getting noticeably longer - roughly 12 hours of daylight compared to 11 hours in January - and the weather starts its gradual transition toward the drier summer pattern.

North Shore surf on Oʻahu begins declining from its winter peak but remains active through March. Waves can still reach 15-20 feet on bigger swell days, and the Vans Triple Crown wraps up in March. By mid-to-late March, north swells ease enough that some North Shore beaches become swimmable again, though conditions vary week to week. Always check surf reports before entering the water.

Spring break crowds

Spring break timing varies by university and school district, but the heaviest period falls between the third week of March and the first week of April. Universities typically break earlier (mid-March); K-12 districts often break closer to Easter (which moves between late March and mid-April depending on the year). The overlap creates a three-to-four week window where Hawaii sees some of its highest visitor numbers and prices of the entire year.

Maui feels spring break most acutely. Hotels in Wailea, Kīhei, and Kāʻanapali can sell out 3-6 months in advance for peak spring break weeks. Rental cars become scarce and expensive. Road to Hana traffic reaches annual peaks. Haleakalā sunrise reservations sell out the moment they are released (60 days ahead). Oʻahu sees similar pressure in Waikīkī, though the larger hotel inventory means slightly more last-minute availability than Maui.

If you are visiting during spring break, book as far ahead as possible and consider the Big Island or Kauaʻi for slightly less crowd pressure (though both still see increases). If your dates are flexible, the first two weeks of March offer good conditions with far fewer people, and the week after Easter (early April) marks the moment when spring break ends and prices drop sharply. See Hawaii on a budget for strategies to reduce costs during high-demand periods.

March highlights

Whale watching (early March): Humpback whale numbers remain high through early March, though they begin declining toward the end of the month as some adults start their migration back to Alaska. The peak breaching and surface activity often occurs in late February and early March before the northward migration begins. Book tours early in the month for the best chances. Mother-calf pairs are still common in early March. Our whale watching guide covers the best operators and locations.

Haleakalā sunrise: March sunrise times at Haleakalā are around 6:15 am, later than January and February and easier to manage logistically. The summit is cold - 30-40°F at the top - so bring layers, gloves, and a hat regardless of the month. The drive from sea-level resort areas takes roughly 90 minutes and begins in complete darkness. Reservations through recreation.gov are required and must be secured 60 days in advance; slots sell out within minutes of release during spring break.

Hawaii Food and Wine Festival: Various food events, tastings, and chef collaborations run throughout March on different islands. The festival showcases Hawaii Regional Cuisine, local ingredients, and visiting mainland chefs. Events sell out early; check the official festival website for dates and locations specific to your travel window.
